Overview

The MAX9061EBS+TG45 is an ultra-small, single comparator designed for low-power applications, operating from a supply voltage as low as 0.9V. It features an open-drain output and integrated RF immunity filtering to maintain performance in noisy environments. With a maximum quiescent current of 1.1uA and a tiny 1.05mm x 1.05mm UCSP package, it is optimized for space-constrained, battery-operated devices.

Why Choose This Part

The primary advantage is the exceptionally low power consumption of 1.1uA max, which is paired with a wide input voltage range of -0.3V to 5.5V. Its integrated RF filtering simplifies PCB layout by reducing the need for external decoupling components in wireless applications. Additionally, the +/-12mV of internal hysteresis provides noise immunity without requiring external feedback resistors.

Applications

Battery Monitoring
Monitoring cell voltages in portable electronics where minimal current draw is critical to extending shelf life.
Threshold Detectors
Acting as a precision level sensor for low-voltage logic signals in mobile handsets and tablets.
Portable Medical Devices
Providing signal comparison in wearable diagnostic tools where board space is extremely limited.
Zero-Crossing Detectors
Utilizing the open-drain output for level shifting and signal conditioning in low-frequency sensing applications.

Getting Started

When designing with this UCSP package, ensure your PCB assembly process can handle the 0.5mm pitch bump array. For initial prototyping, use the MAX9060EVKIT evaluation kit, which provides a platform to test the MAX9060-MAX9064 family of comparators. Place a 0.1uF ceramic capacitor close to the VCC pin to maintain stability, and select a pull-up resistor for the open-drain output that balances speed and power consumption.
